Brief Description

Bagle.UZ is a worm that spreads by copying itself, without infecting other files.

In the local network:
it generates a large amount of network activity and consumes bandwidth.

It reduces the security level of the computer:
it terminates processes belonging to security tools, such as antivirus programs and firewalls, leaving the computer defenseless against attacks from other malware; it changes system permissions, decreasing the security level.

It uses stealth techniques to avoid being detected by the user:

It uses techniques included in its code to hide itself while it is active.

Bagle.UZ uses the following propagation or distribution methods:

Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.

Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
